12-Bay Rackmount Expansion Unit

The Synology RX1223RP is a 2U rackmount storage expansion unit that adds up to twelve 3.5-inch or 2.5-inch SATA drive bays to a compatible Synology NAS. It ships diskless and connects via a Mini-SAS HD cable included in the box. Redundant power supplies protect against single points of failure. The unit operates from 100 V to 240 V AC and fits standard rack depths.

Ideal for Capacity Growth Without Downtime

This unit suits administrators who need to expand raw storage on a supported Synology rackmount server without interrupting services. It supports adding up to eight expansion units for a total of ninety-six additional bays. Buyers who require a standalone NAS with its own operating system should look at a primary server instead. Environments that need drive interfaces other than SATA are not served by this chassis.

SATA Drive Compatibility Is the Deciding Factor

The RX1223RP accepts only 3.5-inch or 2.5-inch SATA HDDs and SSDs, and Synology guarantees full functionality only with drives on its validated compatibility list. Drives are not included. Confirm that your existing NAS model supports RX-series expansion and that your chosen drives appear on the list before purchasing.

Questions about this item

How can I confirm the RX1223RP is operating correctly after connecting it to my Synology NAS?

The unit will appear in DSM Storage Manager once the Mini-SAS HD cable links it to a compatible Synology server, and all 12 drive bays show healthy status with no degraded volumes.

What ships with the RX1223RP and what must I purchase separately?

The box contains the main unit, two AC power cords, one Mini-SAS HD expansion cable, an accessory pack and a quick installation guide; 3.5" or 2.5" SATA drives are not included and must be bought separately.

Which RX1223RP configuration should I choose for maximum raw capacity?

Only one hardware version exists — a 12-bay 2U rackmount unit — so capacity depends on the SATA drives you install; eight units can scale a compatible system to 1.7 petabytes raw.
